7.10 Center Ski Case Width Dimension ‘D2’ Adjustment
Before making any machine
adjustments, refer to the shutdown
procedure outlined in Section 6.5:
‘Shutdown’
.
The center ski that serves to
passively fold down the leading
bottom minor flap is mounted on a
slotted bracket that permits the ski
to be adjusted forward towards, or
away from, the machine infeed. It
is used to fold the leading minor
flap as the case is pushed into the
conveyor and flap folding section of
the machine.
Its position is affected by the width of the case due to the fact that with the most common RSC
style case, all the bottom flap heights or widths are ½ the width of the case. The ski must be
positioned so that it will not interfere with the folding of the rear minor flap by the active folder.
This adjustment is generally less critical than the other case width adjustments and for most mid-
size cases it will probably be possible to find a position in the middle of the adjustment range that
will suit them all. Its position is more critical with the smallest and largest size cases.
When running cases with widths that are close to the
machine’s minimum or maximum limits, it may be
necessary to adjust the position of the ski to ensure
that the minor flaps are folded correctly. To run most
case widths that are close to the machine’s average
width capabilities, the ski should be set at roughly the
midpoint on its mounting slot. For cases that are close
to the machine’s maximum width capability, or cases
with a larger than normal minor flap height, the ski
should be adjusted away from the machine infeed,
such that the rear minor flap does not contact the ski
before it is fully folded up.
For cases that are near the machine’s minimum width capability, or cases with a smaller than
normal minor flap height, the ski should be adjusted toward the machine infeed, such that the
rear minor flap does not spring open before it reaches the ski and is guided above it. In general,
the minimum distance between the bottom of the folded rear flap and the center ski should be 1”.

Loosen the bottom center ski quick-adjust handle.
Reposition the ski along the scale until the ‘D2’ pointer matches the
measured formed case width, or until the clearance between the arc
of the bottom flap as it’s being folded and the center ski is at least 1”.
